Ha! I just had an idea. Imagine the backstory of Sam and Dean was different. What if from the beginning they were reincarnation of Michael and Lucifer. So both angels were at war. Because God loved them so much , he couldn’t see his children fight one another and decided to end them and bring them back in a human body, meaning in baby Sam and Dean. As kids they are very normal but with time as they grow older they discover they have powers. They don’t know what’s happening to them and start investigating the supernatural and the lore. One day Castiel shows up and tells them who they are. Throughout the show they are fighting with their past life and destiny. However their love and connection as Sam and Dean is so much stronger than their past life that they learn to forgive one another and they continue to hunt monsters together. So to make things clear, many things that happened in the show can still happen but no such thing as Lucifer and Michael jumping from body to body. They cannot separate themselves from Sam and Dean because they are bonded to them. Yes the show would have been different in some ways, but not too different plus would have given some more action and consistency :)
Also do you have a twitter/tumblr that you've linked this on? I don't know you but I'd love to post/reblog it from the source to get traction to your SM directly.
